MUFFLER
Inspect and replace corroded muffler as it could create a
fire hazard and/or damage.
Clean the underside of your lawn mower by scraping
to remove build-up of grass and trash.
Clean engine often to keep trash from accumulating.
A clogged engine runs hotter and shortens engine life.
Keep finished surfaces / wheels free of gasoline, oil, etc.
We do not recommend using a garden hose to clean
lawn mower unless the electrical system, muffler, air
filter and carburetor are covered to keep water out.
Water in engine can result in shortened engine life.

HOUSING FREE OF BUILT-UP GRASS AND TRASH. CLEAN
THE UNDERSIDE OF YOUR MOWER AFTER EACH USE.
CAUTION: Disconnect spark plug wire from
spark plug and place wire where it cannot come
in contact with plug.

WATER WASHOUT FEATURE
Your lawn mower is equipped with a fitting that allows quick
and easy cleaning of the underside of the housing. To use
this feature, proceed as follows:
1. Move lawn mower to an area of cut grass or another
hard surface.
NOTE: Water, grass and other debris will drain from beneath
the mower housing during the washout process.
2. Remove grass catcher and discharge chute assembly
from lawn mower.
3. Close mulcher door (if equipped).
4. Connect a garden hose to the fitting where shown
(Figure 26).
IMPORTANT: BE SURE THE GARDEN HOSE IS NOT ROUTED
UNDER THE LAWN MOWER HOUSING OR ENTANGLED IN
THE WHEELS.
5. Turn on water supply and check for leaks at the fitting.
If no leaks are present, start engine (as described in the
Operation section of this manual) and let engine run until
the underside of the lawn mower is clean.
WARNING: Do not engage the drive system during
the washout process.
CAUTION: Do not remove hose from fitting while
engine is running. Water in engine can result in
shortened engine life.
8. Start engine (as described in the Operation section
